I have been looking for OEM Soobie wheels for my 2001 Forester.  The current wheels are 17" really ugly, hand painted white rims.  The car has been lowered about 1.25 inches.  The tires right now are 235/50/17.  I found a good deal on a wheel and tire combo on Craigslist, from a 2008 Impreza.  Stock 16" rims with tires 205/55/16.  The only real difference I noticed in the rims/wheels is the offset, which is a mere 7 mm.  The Impreza wheel offset is 55mm and the Forester is 48mm.  Is that amount of offset going to cause trouble?  Using a measuring tape, and eyeballing it, it doesn't seem like the tires will rub when the wheels are turned.  I'm also going to raise the car back up to stock the near future.  

Should be no problem.
